After you play an ally, Vorhild deals 1 damage to a monster engaged with her.
Exhaust: For the remainder of the turn, reduce all damage dealt to and dealt by Vorhild to zero. (Does not prevent extra trample damage.)

Question: How does trample work against Vorhild when exhausted?
Answer: If an attack of 4 with trample is coming in towards Vorhild, 1 damage of that would be combat damage and the other 3 damage would be trample damage. By using her ability, you only prevent the 1 damage and the trample damage would still hit the castle.
